Insulator structure



Nov, 8, 1932. H. c. sTAToN INSULATOR STRUCTURE Filed June 20, 1928Patented Nov. 8, 1932 rumen-K PATENT OFFICE HARRY C. STATON, OFBURLINGTON, IOWA INSULATOR Application led .Tune 20,

The object of my invention is to provide an insulator structure ofsimple, durable, and comparatively inexpensive construction.

A further object of my invention is to provide an insulator especiallyadapted for use in the electric and radio iield in which novel means ofconnecting the wire to the insulator and of anchoring the insulator to asupport is provided.

More particularly, it is my object to provide an insulator in which abody portion formed of porcelain or other suitable insulating materialis provided in combin ation with an anchoring rod of irregularconiiguration, the insulator body being formed with an opening of suchshape to allow insertion of the anchoring rod whereby the insulator bodymay be supported relative to the anchoring rod.

Still a further object is to provide in connection with the anchoringrod, an L-shaped brace adapted to prevent straightening out of theanchoring rod when the insulator structure has once been assembled.

With these and other objects in view my invention consists in theconstruction, arrangement and combination of the various parts of mydevice, whereby the objects contemplated are attained, as hereinaftermore fully set forth, pointed out in my claims, and illustrated in theaccompanying drawing, in which:

Fig. l is a plan view of the insulator body.

Fig. 2 is a side elevation of the same.

Figure 3 is a sectional view through the insulator body showing ananchoring rod and a brace for the insulator body.

@n the accompanying drawing, I have used the reference character A todesignate generally, the body of the insulator structure. The bodyportion A is formed of porcelain or other suitable insulating` materialand is provided with an opening 10. The opening 10 runs through theinsulator from top to bottom and has a cutaway portion indicated at 12.

STRUCTURE 1928. Serial No. 286,755.

A groove 14 extends lengthwise of the body A from the opening 10 to oneend of the body. An opening 16 extends through the insu lator from sideto side for the purpose of receiving an electric wire or a tie wire, asthe case may be. Each side edfre of the body A is grooved as indicatedat 18 and one end thereof is grooved as indicated at 20.

In Figure 3 of the drawing, I have shown an anchoring rod C which isscrew threaded, as indicated at 38 to receive a nut 40. The anchoringrod C may extend through a pipe 42 or any other type of support throughwhich an opening can be provided, so that the nut 40 can be positionedon the side of the support 42 opposite the insulator A. rIhe anchoringrod C ext-ends along the insulator A in the groove 14, as clearlyillustrated, and is provided with a nut 44. To prevent straightening outof the anchoring rod C, I provide a brace strap 46 made of liat materialhaving openings punched in its ends so that the strap 46 may extendalong two surfaces of the insulator A and be associated with portions ofthe rod C extending at right angles to each other. If desired, the brace46 may be formed oi heavy wire having eyes proided in its ends. Vhenarranged as shown in Fig. 6, the dead ended wire 30, in the event. thatthe insulator A is broken, will not drop onto the ground, but will becaught by the anchoring rod C.

It will be obvious that various changes such as in the configuration ofeither the insulator body A or the anchoring rod C may be made withoutdeparting from the real spirit and purpose of my invention, and it is myintention to cover by my claims, any modified forms of structure or useof mechanical equivalents, which may be reasonably included within theirscope.

I claim as my invention:

1 An insulator comprisinor a body portion having an opening therein, ananchoring rod having a shank and an angularly extending portion receivedin said opening, a substantially L-shaped brace having its endsreceiving the shank and the angularly extending portions of saidanchoring rod to prevent the same from straightening out and a secondopening in said body portion for receiving a Wire to be anchored to theinsulator.

2. An insulator comprising a body portion having an opening therein, ananchoring rod having a shank and an angularly extending portion receivedin said opening and a substantially L-shaped brace having its endsreceiving the shank'and the angularly extending portions of Saidanchoring rod and preventing it from straightening out.
